I've noticed this on my 97. When I turn the actual heat/cool control from full cool to about mid-way between cool and warm, then back to cool, the air immediately kicks in cool. I think it might have something to do with the switch going out or maybe having something blocking the contacts within the switch (dust, etc.). Try that before tearing the entire dash out trying to fix it.

Unfortunately, the switch is working quite well. The resistance changes smoothly across the range.
